TE Coolers

Originally MD03 Series was developed as a successor of the MD04 Series, mainly focusing on modern trends in the telecom industry - lower current, higher voltage. Single-stage thermoelectric coolers in the MD03 Series are primarily optimized for telecom applications, especially TO-can TOSA and similar products. MD03 TECs are based on our Advanced HD technology with 400 BiTe pellets per cm2 density. By performance-price factor single-stage thermoelectric coolers from MD03 Series take the golden mean between MD04 and MD02 Series. A reasonable balance between TEC current and voltage, small size and affordable pricing make MD03 thermoelectric coolers optimal for telecom applications with a price pressure factor. The standard and most common single-stage types from our MD03 Series are listed in the table below. All thermoelectric coolers are assembled using RoHS compliant Sn-Sb solder with a melting temperature Tmelt=230ºC. Thermoelectric coolers of MD03 Series all meet Telcordia GR-486 standard requirements. A wide range of TEC manufacturing options is available. Detailed TEC drawings, 3D models, performance plots and estimations for particular application conditions can be provided by request.
